i totally understand and agreed with you but i am just saying what Samsung engineers thought to there service center technicians and instructed to do as per proper procedure, load all the files and flash it they do this for all the device any Samsung phone down grade up grade or same reflash they do the same sorry if am wrong but am just saying in the official way rest all on us...
I remember reading on XDA that a member asked the service center guys about rooting and they did not know what it is
So I'd rather go with what the devs say. :laugh:
